Unfortunately this seems to have coincided with an eczema flare up, and the great sage that is Wikipedia is advising:
The first and primary recommendation is that people suffering from eczema shouldn’t use detergents of any kind unless absolutely necessary. Current medical thought is that people wash too much and that eczema sufferers should use cleansers only when water is not sufficient to remove dirt from skin.
Interestingly this seems to be serving me quite well. Cutting back on soap has spared me from spending the morning itching, a significant problem just a few days ago. The only problem now, though, is personal hygiene.
If you happen to be walking past me any time soon and I offend your nostrils, please tell me.
